To all whom t may concern.'

Be it known that l, EDWIN D. CODDING- ron, a citizen of the United States, residing at North Milwaukee, in the county of Milwaulree and State of Wisconsin, have invented certain new and useful improvements in Grounds for Cement- Coated Walls, of which-the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

'.lhe main objects of this invention are to provide a simple, cheap andconvenient substitute for wood and metal lathing, and to facilitate and improve the construction of plastered or cement coated walls.

llt consistsin the construction, arrangey ment and combination of parts as hereinafter particularly described and pointed out in the claims.

ln the accompanying drawing like characters designate the same or similar parts in the several figures.

Figure l is a side elevation of one of the' embodimentof the invention specially de-u signed for roofing or similar purposes where ttl the ground or backing is to be coated on one side only; Fig. 5 is an elevation of another modication showing a diderent arrange` ment of the reinforcing wires; Fign 6 is a section on the line 6 6, Fig. 5; Fig. 7 is an elevation showing another method of fastening adjoining lapped sheets together and to a girt or frame member; Fig. 8 is a like view of another modification; and Fig. 9 is a silar view showing portions of adjoin ing lapped sheets with reinforcing wires extending across the-'lap4 and interwoven through both sheets and with one another.

Fteferringto Figs.; l. and 2showing a construction of the ground or backingdoubly `reinforced and specially designed to receive a plastic coating on both sides, c designates .l dexible sheets of fibrous mate-1 rial, such as commercial building felt orl paper, whichis ordinarily and preferablysaturated or coated with a tar product or the like, to renderI it waterproofB ilhese sheets are reinforced at intervals by wires to render` them sufficiently stiff and stable to receive a coating of plaster or cement on each or either side when the ground or backing is spread upon and attached to the-framework of a wall or partition the members of which may be spaced according to the nature of the .structure more or less widely apart, thereby elfecting not only a saving in material, .but also in the time and labor required for erection.

ln the present case the ground or backing sheets a, are each provided with three series 'or sets of reinforcing wires b, c and d. rlhe wires b are woveny at suitable intervals in and out through the sheets c, preferably parallel with one another and at an oblique angle to the longitudinal edges of the sheets at or 'adjacent to which they terminate..

rlhe wires c and d of the other two sets or series are interwoven with the sheets a and wires Z) alternately on opposite sides of the sheets, and preferably parallel and equidis tant from one another at an oblique4 angle to the longitudinal edges of the sheets and to the wires o. rlhe wires c are preferably located entirely on one side of the sheets c, while the wires al' are located entirely on the opposite side of the sheets, and they may be insertedunderneath all of the wires Z5,

tid

which they cross, as shown, or they may be woven in and out underneath and over some of the wires b, or like the wires. t through the sheets, to more securely confine them in .place on the sheets before the plaster or cement coating is applied thereto. -ltlard drawn or resilient wire is preferably used for the reinforcement of this form of the ground or backing, which may be prepared in a shop or factory ready for use, -and rolled for storage and transportation, the wires assuming a spiral form when the sheets are rolled, but on account of ytheir resiliency resuming a straight form when the sheets are unrolled and spread dat. 'File sheets are lapped when or before they `are applied to the framework of a wall, and are fastened together along their lapped edges 1n varlous ways.

is shown in Figs. 'l and 3, where the sheets c are separately reinforced by wires terminating at Itheir ends at or adjacent to the longitudinal edges of the sheets, the lapped portions of adjoining sheets may be fastened together by a sheet metal strip c, having prongs f passing through the sheets lill@ and clasped over a wire g lon the opposite side of the backing.. This method of fastening is specially designed for use where the lapped joint between the sheets is unsupportedby a girt or frame member.

Where the lapped joint overlies a girt or frame member, such as la, as shown in Figs.

'7 and 8, the lapped edges of adjoining sheets may be fastened thereto by nails alone, by a one, for-'storage and transportation.

For certain purposes, as when the ground or backing sheets are to be'coated on one side only, one or both of the'extra sets of rein-y forcing wires c and d may be omitted, and the wires ma be spaced more or less closely.

'Wires of di erent sizes and diderent shapes `1n. cross sectlon may also be used for reinforcement of the same sheets, larger wlres or rods alternating with smaller wires or rods, orybe'ing placed at more or less frequent intervals, according to varying conditions and requirements.

For roofing or other purposes, where the ground or backing sheets a, are to be coated on one side only, and wherean imperforate water tight base or foundation is desirable, the`wire reinforced sheets a, may be backed by an extra sheet Z, of building felt, paper or other suitable material, attached thereto by any suitable adhesive substance suchasl cement, tar, pitch or the like, asshown in Fig. d. 1n this case the sheet a has but one extra set of reinforcing wires c, which are applied thereto on the side opposite the backing vsheet Z, but sheets reinforced as shownv 1n Fig. 1,' may be provided with backin sheets cemented thereto.

he reinforcing wires may be applied to 1the sheets at vright angles to and parallel with their longitudinal edges, as shown in Fig. 5. 1n this case, in which the sheets are not intended to be rolled for transportation or storage, the wires are not necessarily hard' drawn or resilient, but may be more or less annealed and flexible. With this arrangement, in which the cross wires b are threaded or woven at intervals through the sheet @and the longitudinal wires c". and d are interwoven-with the sheet and with the wires b on oppositel sides of the sheet, either er both sets of the vextra reinforcing wires c and d may be omitted.

lapped sheets may be fasmesses In the several embodiments of the device herein shown .and described, the wires b or b being threaded or woven at intervals through the sheets a, form an integral structure, and no extra fastenings are required to secure the wires to the sheets, the. wires being held in place by frictional engagement with one anotherand with the faces of the sheets.. The threading or weaving of the wires b or b through the sheets, and the interweaving or insertion of the extra reinforcing wires c or c' and d or d between the wires o or b and the sheets, cause the sheets to assume a corrugated undulatory, or wavy form, as shown in Figs. 2 and 6. This gives the plastic coating m, applied to one or each side of the sheet, a corresponding corrugated undulatory, or wavy form, which materially stifi'ens and strengthens it between the members of the framework to which the ground or backing sheets are attached, so that much wider spaces may be spanned than would otherwise be practicable with a comparatively thin coating of plastic material, the ridges or thicker portions of the coating actin as beams ortrusses between the supporting members of the framework.

While the coating fm, of plastic material will adhere with tenacity to the rough fibrous surfaces of the sheets or, it is further secured thereto by thereinforcing wires around which it flows, and which are embedded therein, the plaster or cement formf ingkeys or clenches around and enveloping the wires and sealin the openings in the sheets, as shown in Fig. 2, without waste of material in the formationV of the keys or clenches.

The wires '12, c and al and the wires o', whether they terminate at the edges of the sheets a, asshown in Figs. l, 5, 7 and 8, or

. cross ad'oinin sheets as shown in Fi 9 extend across the lapped portions of ad]oining sheets to which they are attached, and form continuous reinforcements in the direction of the length of such wires spanning the joints between the sheets.

Various modifications in minor details of construction other than those S ecifically shown and mentioned, may be ma e without departure from the principle and scope of the invention as defined 1n the following claims.

The term cement as herein employed, is used in its generic sense, and includes any plastic material suitable for the purpose, and the term wall is intended to include horizontal, perpendicular and inclined structures, such as the outside walls, partitions, floors, ceilings and roofs of buildings.
